T0 all whom Zt mag concern:

Be it known that I, DIXON E. VASHING- TON, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inRazor-Stropping Devices, 0f Which the following is a specification.

This invention .relates t0 stropping devices and has for it-s primaryobject to provide an improved construction, combination and arrange-ment0f arts in a device 0f this nature.

More specifically, the object of this invention is t0 provide animproved device 0f this nature whereby both faces of the same edge 0f arazor blade may be simultaneously stropped.

Another object is t0 provide improved blade holding means permitting theendwise introduetion and withdrawal 0f the blade.

Other and further objects Will appear in the specification und be morespecifically pointed out in the claims, reference being had to Cl1accompanying drawings exemplifying the invention, and in which Figure 1is a side elevation of the stropping device constructed in accordancewith the principles of this invention. Fig. 2 is a longitudinal section0f the same 011 the line 22 0f Fig. 3. Fig. 3 is an end view taken fromthe left end or Fig. 1. Fig. 4: is an enlarged detail view of the bladeholder. Fig. 5 is a section 011 the lilie 5 5 of Fig. 2. Fig. 6isaperspective view 0f portions of the sleeves employed in the presentembodiment 0f the invention. Fig. 7 is a detail end view 0f one 01 thelocking pins.

The present invention consists in the C011- struction, combination andarrangement of parts shown in the drawings and in die feaures of noveltyexemplified therein.

According to the preferred embodiment shown and described, the device ismore especially adapted for stropping safety razor blades, particularlythose blades provided with perforations for securely mounting them in ahandle, but with modifications in the holder, said device may he adaptedfor use in connection with many other articles 013 similar construction.

Referring more particularly t0 the draW- ings, the features of invention%LI'G embodied in or conneeted with a combination of a blade holder, astrop-guiding device between which and the holder relative movement ispermitted, said guiding device being provided with means for pressingtwo sections 0f a strop against opposite faces of the same edge of ablade, and means for damping said edge during the stropping operation.

Preferably, the hlade holder consists 0f a rod 1 adapted to releasablyengage a blade 2 by heing provided With a slot 3, preferably in 011e endof the rod l, and by mounti11g in one of the segments 4, 5 into whichsaid rod end is divided by the slot 3 one or m ore pins 0r tumblers 6,6, f0r detachably engaging in the perforations commonly provided in wellknown types of blades. In order to provide means f0r resilientlypressing the ins 6, 6 against the other seg- 1nent 5, a spring 7,preferably of wire, is passed through perforations in the outer ende ofthe pins 6, 6, and fastened in any suitable manner, as at 8, t0 thesegment 4. The inner ende of said pins are beveled 011 the sides facinglongitudinally 0f the slot- 3, While the sides facing laterally 0f saidS101; extend perpendicularly down t0 the flat surface of the segment 5.111 this way 'said holder is adapted to permit the endwise introductionand withdrawal 0f ablade while said blade, alter it has been 1nsertedinto position, is rigidly maint-ained agamst lateral move1nent by reason0f the perforations therein heilig loeked against the sharp corners ofpins 6, 6.

A suitable strop-guiding device for the sections 9, 9 0f a strop, whichseetions may be portions.of a single strop 01 the parallelly disposedportions 0f 1;W0 strops, is prefer ably provided by movably mounting apair of plates 10, 11 0n Opposite sides of die elotted end of the holder1, said plates being preferably curved as shown to permit the stropsections t0 slide easily thereover. Confiiguously t0 the lateral edges0f the plates. 10, 11 are mounted strop supports, which may be of anysuitable form. Preferably, however, said supports are provided in theform 015 rollers 12, 13, 14 and 15,

suitably journaled between bosses 16 and ears or lugs 17, said bossesand ears being integrally formed 011 said plates 10 and 11respectivgaly. Preferably integrally formed With the platze 10 and thebosses 16 thereon, is a hub or collar 18, by means of Wl1lCh said plateis rotatably mounted, preferably upon the blade holder l. In a si1nilarmanner, the plate 11 is also rotatably mounjaed by means of a hubportion 19. Referr1ng now more espeeially to Figs. 2, 5 and 6, 1neansfor resiliently mounting said plates 10 and 11 out of engagement Withthe blade carried by the blade holder 1 may be provided in any suitablemanner, but according 1 0 the present embodiment shown on the drawing,said means comprises a sleeve 20 rigidly oonneoted 130 the hub 18 of theplate 10, and a sleeve 21 rigidly oonneoted With the hulo 19 of theplate 11, said sleeves being concentrically mounted to rotate relativelyto the blade holder 1, and 130 eaoh other about the axis of said holder.Rigidly mounted on the outer extremity of the inner sleeve in anysuitable manner is a disk segment 22 (see Fig. 6), while upon the outerextremity of the outer sleeve 21 Which is rotatably mounted in a handle28 and terminates short of the sleeve 20, is a disk segment 23. Saiddisk segn1ents are provided respectively Wih not-ches 24, 24, and 25,25, wherein engage Ehe ende of springe 26, 27, preferably made of wireand mounted in the manner shown in Fig. 5. Intermediately of their endssaid wire springe are rigidly connected with the outer extremity o1 theblade holder l, preferably by being passed through a slot o1 hole extending therethrough. Said springs are suitaloly fashioned and disposedto normally maintain the rollers 12, 13, 14 and 15 equally distant fro1nthe plane of the blade 2.

It Will 110W be, readily understood that upon producing relativemovement between the strops and blade holder, such as by 1noving theholder fro1n left to right, as indicated in Fig. 3, the taut portions ofthe strop seotions Will force the blades 10 and 11 into clampingengagement with both faces 01 the left band edge of' the blade, while atthe sa1ne time the rollers 12 and 13 Will force the strop seetionssimulta neously against both faoes of said edge. As soon, however, asthe movement is reversed the strop portions on the left beeoming slackper1nitthe blades 10 and 11 to return to normal osition under the aotionof ehe springe 26, 27, while the portions of the strop to the rightbecoming in turn taut, Will throw the blades 10 and 11 into clampingengagement with the other edge of the blade and also press the stropsections simultaneously against both faoee of that edge. It will thus beseen that in whiohever direction the blade is moved with respect to thestrop, the 'sections 01: said strop Will loe drawn outwardly over bothfaces of one edge ab the same ti1ne, thus preventing a turned or wiredravvn edge.

What I claim is:

1. The comhination of a strop having two sections, means for holding adouble-edged blade therebetween, said means being movable sucoessivelyin opposite direetions relatively to said sections, and means forcausing simultaneous engagement between the strop sections and bothfaoes of one edge of the blade when said holding means is 1noved in onedireotion and :Eor causing a simultaneous engagement betvveen said stropsections and both faces of t-he other edge when the holding 1neans ismoved in the' opposite direction.
